Nice hit. Sorry, don't know Prizm very well - are the greens #'d? I'm assuming they are retail exclusive? In short, why so valuable?

They aren't numbered, but retail of this product seems to be very limited. You only get around 2 greens per box I believe and if you search eBay, it's hard to find a certain player with more than 1 or 2 cards that have been listed.

For those who are asking about buying, it's going on eBay as we speak auction style 24 hours.
